Upgrade Kaspersky Security Centre 8 to 10?

Hi,

We are looking to upgrade from Kaspersky Security Centre 8 to 10. We are planning on building a test environment (and thus building a fresh server for this project). When testing is completed, how is it best to move the clients from from 8 to 10? We have 2,000 clients approx, so this will be staggered method.Can i copy the agent and av policies over? Anything else i need to be looking at?

Kaspersky server 10 will be: 2008 R2. sql 2008 will be on a separate server,

clients: Windows 7 Enterprise SP1.

Thanks for reading this
